Air is compressed under steady flow conditions, see Figure Q3. The power input to the compressor is 3 kW. During the process the specific heat loss from the compressor is measured to be 20 kJ/kg. The mass flow rate of the air is 0.04 kg/s. The velocity of the air entering the compressor is 3 m/s, and the velocity of the air exiting the compressor is 10 m/s. The compressor outlet is 10 m below the compressor inlet. The specific enthalpy at the compressor inlet is 280.13 kJ/kg.
(a) Calculate the specific enthalpy at the compressor outlet. Include in your calculations the changes in kinetic and potential energy.
(b) Neglect the changes in the kinetic and potential energy and re-calculate the specific enthalpy at the compressor outlet. What effect does this have on your value for the specific enthalpy at the compressor outlet?
(c) If the specific internal energy increases by 39.32 kJ/kg during this process, find the change in temperature of the air between the and outlet of the compressor.h = 280.13 kJ/kg ,h = 280.13 kJ/kg,Inlet Compressor m=0.04kg/s,Power input=3 kW,Outlet h=?Note: You may assume that air is an ideal gas.
